L2TP ping between routers but non LAN

Hi guys,
I don’t know very much about Routerboard but I’m trying to learn!
I’ve managed to establish a L2TP VPN between 2 RB951. The server behind a firewall (I’ve forwarded the requested ports) and the other is connected to a public wireless.
The L2TPconnection is UP and I can ping router1 from router2 and vice versa but I can’t ping from routers to the other LAN or from LAN to LAN.
What I’ve done is:

  • router1: created the L2TP server
  • router1: added route for LAN2 through L2TP
  • router2: created the L2TP client
  • router2: added route for LAN1 though L2TP

What else am I missing?
Thanks,
Andrea

Hi.
You can add your config prints here, so people can help you out.

Did you enable proxy-ARP?
